# Zero Cool documentation

All documentation is public.

## Install the CLI

```sh
curl -fsSL https://app.zerocool.ai/cli/install.sh | sh
export PATH="$HOME/.local/bin:$PATH"
zerocool auth login
zerocool auth status
```

The installer needs Python 3.9 or later and curl.
Open the login link in your browser and approve it. The CLI creates and saves your new API key.
You do not need to create or copy a key first. Use the CLI for audits and automation.
Read https://zerocool.ai/docs/get-started for the complete setup and page list.
With the CLI, run `zerocool docs [page]` or `zerocool docs search <term>`.

## Coming from Nexus?

Re-register at https://app.zerocool.ai with the same email to keep your workspaces.
The old api.zerocool.ai service is retired, and old API keys no longer work.
Install the new CLI, then run `zerocool auth login` to create and save a new key through browser approval.
